Description
If you are reporting a bug, please fill in below. Otherwise feel free to remove this template entirely.
Can you reproduce the problem with latest npm?
Many errors, especially related to "missing modules", are due to npm bugs.
If you're using Windows, follow these instructions to update npm.
If you're using OS X or Linux, run this to update npm:
npm install -g npm@latest
cd your_project_directory
rm -rf node_modules
npm install
Then try to reproduce the issue again.
Can you still reproduce it?

Thanks for the report. Unfortunately I'll have to close it because there is not enough information here to diagnose the error, and your best bet is to try to debug the process yourself and figure out what is happening. I'd be happy to reopen if you have any suggestions about what might be happening, or if there are more people experiencing the issue. Since nobody else reports anything like this, it seems like it's some isolated issue with your machine, and even though I'm really sorry this is happening, there is nothing I could do to help.

Hi @AJShippify, not sure you're still having this problem, but it seems I'm running into the same issue when building my app on my Linux box, which is a cloud instance running CentOS 6.5. Anyway, I found that my builds would run briefly, then just stop for no reason. I had a look at the
build.jsscript innode_modules/react-scripts/and was able to track down the config details, and thebuild.jsfile. From there I added theCaseSensitivePathsPluginto watch WebPack load up all the modules, and I found that loading stopped when it got tonode_modules/core-js/library/modules. At that point, everything stopped but no error was provided as to why loading failed.Do you (or anyone else reading this) know of a way to get WebPack to throw some sort of error when it fails to load something or to otherwise make it more obvious why loading failed?
Hope that all helps, or at least provides some clue as to why our builds are failing on Linux. Thanks!

Thanks for sharing the details!

Agreed. Thanks for the clues, @AJShippify. I tried my build on another cloud instance with a lot more memory and things worked swimmingly. In this case, it was an EC2 instance sized at m4.large (16GB memory) which did the trick.
